Black Ops 1 and 2 are not available on the PlayStation 4 (PS4) due to several reasons. One of the primary reasons is that both games were developed for the previous generation of consoles, specifically the PlayStation 3 (PS3), Xbox 360, and PC.

Playable in both 3D and non-3D on the Xbox 360, PlayStation 3 and PC. Call of Duty: Black Ops for Windows PC is NVIDIA(R) 3D Vision(R)-Ready and supports stereoscopic 3D gaming using 3D Vision active-shutter glasses and NVIDIA GeForce GPUs.

Black Ops 3 is arguably the longest Call of Duty game. Most people report finishing the main story in about nine hours, which is certainly a respectable amount of time for a first-person shooter that releases just about annually.

The campaign story was average, the multiplayer was really good, the zombies was an outstanding masterpiece.
